The Sir Hans Sloane Birthday Collection: Giants’ Shoulders #70

Sir Hans Sloane, collector and physician, was born on 16 April 1660. To celebrate his 354th birthday, I’m hosting the history of science carnival: Giants’ Shoulders #70. Sloane collected stuff of all kinds, from curiosities (natural and man-made) and botanical samples to manuscripts. He was very thorough… So what does one give the man who had (nearly) everything for his birthday? The gift of knowledge! Hosting Giants’ Shoulders follows–in a small way—in the footsteps of Sloane, who edited the Philosophical Transactions of the Royal Society for two decades.

As President of the Royal College of Physicians from 1719, Sloane also would have been familiar with medical disputes and prosecutions against irregular practitioners, such as “Master Docturdo and Fartado: Libellous Doctors in Early Modern Britain”. A post on “The Return of Nicholas Culpeper” finds the traces of Culpeper’s career around London. I’ve often wondered whether Sloane would simply have seen Culpeper as an irregular practitioner, or appreciated what they had in common–botanical interests and willingness to treat the poor.

A driving factor in Sloane’s career was his insatiable curiosity. A teacher tells us why the history of science “is essential to engage students”, while “Hydra meets Handel” shows children participating in early modern science by gathering “duck pond detritus”. Sloane also encouraged curiosity in others, including women; for only two examples, he exchanged letters and botanical samples with the Duchess of Beaufort and Cassandra Willughby. There were lots of early modern women who practiced science—and this month, there were posts on Margaret Cavendish, Emilie du Chatelet and Caroline Herschel. Women could also be important patrons of science, such as Angela Burdett-Coutts. (Sloane certainly benefited from the patronage of women early in his medical career, particularly that of the Duchess of Albemarle.)

One of the reasons that Sloane was so well-known for his botanical expertise is that he had actually travelled to Jamaica early in his career, gathered local knowledge and tried out local remedies. On behalf of the Royal Society, he also requested that some explorers bring back specific items or look into particular issues. In 1700, Edmond Halley returned to St. Helena and reported on the area. Halley’s travel descriptions weren’t intended for the Royal Society, but his travels would certainly have been of interest. Explorers have also been the mappers of new and old areas. There is a series of posts on “A Concise History of Geological Maps”, which highlights the many uses of mapping beyond the geographical (2, 3 and 4). The newest areas are sometimes very far away, such as Martian canals or the centre of the Earth. Getting to some places might have been impossible in the nineteenth and early twentieth centuries, though astronomical photography might help to span the distance. But in the end, the question remains: we can take humans out of their usual lands, but can we take the terrestriality out of the humans?

Happy reading! See you next month over at The Renaissance Mathematicus, where Thony Christie will be hosting Giants’ Shoulders #71. His contact details are here, if you want to start sending in nominations for May.
